I have 1 infield sites for michigan international speedway nacsar weekend, June 12th-14th. You can go in anytime after track activites on thursday and stay until monday. These are just 2 sites only. Sites are right next to each other, and walking distance to bathroom and showers. No wristbands, you will need to purchase some at $100 a piece and they will be good for all weekend. (kids under 12 are free), i think.
